An adjustable prosthetic arm powered by mechatronic systems capable of osseointegration based and non-osseointegration based attachment via adjustable socket.

A hand orthosis for bending and/or stretching at least one finger of a patient's hand, comprising a force-introducing device fastened to a splint, which is coupled with at least one finger segment paired with the finger of the patient's hand, wherein the at least one finger segment comprises a plurality of modular members interconnected in an articulated manner. The modular members each have at least one bayonet link on a first front side and at least one bayonet hook, corresponding to the bayonet link, on a second front side for the formation of a bayonet connection between adjacent modular members providing a bayonet joint. In addition, the invention relates to a modular member for using in a hand orthosis and a method of producing a hand orthosis.

The application discloses an antagonistic drive device which adopts capstans and tendon transmission. The device adopts a pair of rotary actuators which are fixedly connected with the capstans of their respective output shafts respectively to drive the controlled joint and constitute an antagonistic drive. Since the rotary actuator can use a small rotary motor, and the capstans can be arranged properly to make full use of the space in the dexterous hand (especially the forearm) or the robot body. The device has the advantages of small overall size, light weight and low noise, which is especially suitable for driving the joints of dexterous hands with small overall size and a large number of joints. It can also be used for driving the joints of other robots.

This application discloses a dexterous hand. The dexterous hand uses the anatomical structure of human hands for reference. The joints adopt dual-actuator antagonistic drive, which gives consideration to both compliant operation and robustness. The tendon joint and tendon sheath fixator are used for easy disassembly of hands and wrists. The metacarpophalangeal joints of each finger have the DOF of circumduction of, so that the fingers can automatically adapt to the complex surface. The axes of the multi-degrees of freedom joints are orthogonal, which is beneficial to control and motion planning calculation. The dexterous hand is ideal for handling objects of complex shape smoothly, facilitating production, disassembly and maintenance.

An under-driven prosthetic hand with a self-adaptive grasping function is provided, which belongs to the field of medical equipment. The prosthetic hand simultaneously controls four fingers to implement bending and stretching movements by a first motor through structural designs of a prosthetic hand body, a finger transmission module, an inter-finger transmission module, and a thumb driving module, and limits the transmission torque between the motor and screws using a damping shaft and in cooperation with the telescopic characteristic of a telescopic component. On the one hand, mechanical damage to the prosthetic hand structure due to excessive torque outputted by the motor can be prevented. On the other hand, the self-adaptive grasping function of the prosthetic hand can be implemented. The disclosure can also effectively solve issues such as excessive volume or mass of the prosthetic hand, complicated control system, and low operation precision.

An artificial hand suitable for use in humans and robots, includes at least one finger member and at least one thumb member, which is actuated by bending the at least one joint by the motor unit; said finger member comprising one proximal and one middle phalanx consisting of two subparts each, said thumb member comprising one proximal and one middle phalanx consisting of two subparts each, and said two-piece proximal and middle phalanges comprise at least one connection means in grooves extending longitudinally therein, increasing lengths of said proximal and middle phalanges by enabling the two pieces to be set apart from each other.

The invention relates to an automated hand, such as a prosthetic hand. In one form, the automated hand may be fluid compatible. In one form, the automated hand may comprise features to reduce the risk of harm to motors and/or other sensitive components of the hand when subject to an impact. In one form, the hand may comprise a wrist joint configured to allow the hand to curl and flex and/or to rotate. In one form, one or more digits of the hand may be individually controlled. In one form the hand may include a thumb rotation locking mechanism. In one form the hand may be provided with removable grip plates. In one form, the hand may be configured for use as a training hand.

The invention relates to a sensor support (10) for arranging on a prosthesis, comprising a main part (20) for receiving sensors, said main part (20) having a sensor section (25) comprising sensors. The main part (20) has a holding section (30) for holding the main part (20) on a prosthesis part and a knitted fabric tube (21). The holding section (30) has a first knitted structure (32) which allows a secure hold of the main part (20) on the prosthesis part, and the sensor section (25) has a different knitted structure (27) which allows a secure positioning of the sensors relative to the prosthesis part.

A jamming roller lock with a housing and at least two jamming discs, which are arranged in the housing such that they can be rotated and which each comprise at least one recess, in which a jamming roller is located, at least one driving projection and at least one driven projection, wherein the jamming discs are arranged and designed in such a way that a rotation of the jamming discs can be achieved by driving the driving projections and a rotation of the jamming discs is prevented by driving the driven projections.

Underactuated prosthetic hand including base body; first and second prosthetic fingers each hinged to the base body; first control cable; actuator to move the first control cable; and for each pair of fingers second control cable having control ends associated with the first and second fingers; and transmission block to allow first control cable to control second control cable; transmission block includes guide integral with base body and defining sliding axis; movable element sliding along guide; first pulley for sliding first control cable hinged to movable element and second pulley for sliding second control cable hinged to the movable element so actuator, when moving first cable, determines moveable element translational movement to displace second control cable and the fingers; and elastic means opposing moveable element translational movement so the moveable element translational movement opposes elastic means allowing them to facilitate return to moveable element initial position.
